This drawing starts with a large pentagram (10 points, 5 rows). I drew another smaller pentagram inside the inner pentagon (5 more points, 5 more rows). Then I drew one last pentagram, even smaller inside the second (5 more points, 5 more rows). The last 5 rows are drawn from each of the 5 points of the largest pentagram through the center.

The following drawing is only two nested pentagrams, but hopefully, you get the picture.
